The character keeps changing a lot in regeneration of images

Im using "Gemini 2.0 - experimental. I put the creativity really low. The I try to change the dress on a woman. the problem is that it changes to a completely different woman. Sometimes there is no resemblence. I tried to put creativity all the way down, but nothing happened upon generating. Now Im trying at 0,4. Upon trying to change angle I get the same problem.
